@crispianneill: "Hi there - I'm researching the history of Abwehr agents in the UK
during WW2, and was wondering whether anyone could offer me some
guidance on the following points.
When was the last Abwehr agent dropped into the UK? I get the
impression, from reading around, that it was late 1940/41, but there
don't appear to be any clear details on this. Another point which
doesn't seem to be described in great detail is what happened to the
agents once they were captured by the British, or more specifically,
the time it took to process them. I know that some were turned and
became Double Cross agents, and that those who refused to cooperate
were executed, but was there ever a situation where an agent was
interned and then executed after a period of some months? Were agents
ever kept alive because they were deemed useful (without their explicit
cooperation, as in the case of Double Cross) and then subsequently
executed?
Any information gratefully received!"

Are you specifically asking about agents arriving
by parachute? Many agents arrived by other means.
Eddie Chapman (ZIGZAG) was parachuted into
Britain at the end of June 1944.
ROVER (a Polish double-agent) arrived from Spain
in May 1944.
They were imprisoned and interrogated by Special Branch
and MI-5.
It depended on the situation, the character of the agent.
Many, perhaps most of the Abwehr's agents were pro-Allied,
and were taken on in double-cross work as soon as their
bona fides were established.
Some were run by impersonation - MI-5 personnel providing
the messages to Germany. That in fact happened with ROVER,
who would have been a willing double agent. But the Germans
ignored him for a long time after he reached Britain, and
he went off to serve in the Polish Navy. _Then_ the Germans
started calling him, so an MI-5 operator had to imitate him.
Certainly. JACOBS, who landed by parachute on Jan 31 (year
not given, but probably 1940) was executed in August.
Richter, who landed in May 1941, was executed in December.
Almost certainly. JACOBS and Richter probably both fall into
this category. Execution would happen only when there was
no chance of getting any information or other use from the
prisoner.
See _The Double-Cross System_ by J. C. Masterman for a lot
more information.
It's an essential source on this subject.
